Its not a common side effect, but its not outside the realm of probability. Its impossible to give you an online diagnosis and I am not qualified to even make an attempt. What else are you taking, if anything?

The combination of sesame oil, arachidonic acid, fish, and flax oil might be causing your skin to become more oily than usual. Depending on how often you wash, this could very well lead to acne. I'd probably drop back on the fish and flax oil while using HemodrauliX. If that doesn't work, then just discontinue the HemodrauliX.

Question for the Axis rep guys: I was reading about Hemodraulix, and it seemed like a very solid product. Seemed to be the only other product that I could find, besides NO2 Black that was effectively able to activate NOS, thus increasing NO. Really thinking about giving it a shot as soon as my NO2 Black runs out.
My question is: The arachidonic acid works synergistically with the NO? I know that both NO and AA are signaling molecules, I was just wondering how exactly they work together.

It's actually a bit more complex than that. The production of excess sebum in the skin is potentially caused by a combination of several factors. Though it's too much to write on here, i can safely say that the consumption of supplementary oils isn't one of them. In fact, taking fish and flax oil cause the body to produce less oils because of the large amounts of omega-3's being consumed.
Now to answer the earlier question about hemodraulix and acne: It's become common knowledge that a diet with a balanced 1:1 ration of omega-3's and omega-6's is essential to keep acne at bay. now, you're doing great by consuming the omega-3-rich oils, (you're probably doing so to help your complexion right?) but taking hemodraulix can in fact cause acne. I believe you've already had a bad experience with the product from what I've read.
Here's why.
sesame seed oil, which is used as a vector for absortion of the other ingredients in Hemodraulix, is shockingly high in omega-6. this throws off the 1:1 balance you're aiming for by taking omega-3 supplements, and in effect you break out. The only way to counter this would actually be to take more fish or flax seed oil (fish oil actually carries more omega-3/gram).
